namz7791 Posted January 13, 2004 Share Posted January 13, 2004 I to am new to Hybrid Z and have a couple of questions. (I hope 2 questions at once are ok?) Has anyone installed the GM performance parts ZZ4 and if so did the JTR recommended block hugger headers work with the angle plug heads? Also, the JTR recommends a T5 transmission but it doesn;t appear to be rated for the output of the ZZ4. I have a Muncie M21 and wonder if this can be used. The JTR mentions them but only goes into details regarding the T5 and doesn't mention whether or not the M21 will fit and if so what shifter to use etc. Lakewood does make a bellhousing with an Hydraulic clutch attachment to accept the M21 straight up. Thanks in advance for all your help! Quote Link to comment Share on other sites More sharing options...
Mike C Posted January 13, 2004 Share Posted January 13, 2004 The L98 heads are funny, but there are some shorty headers that will work with the GM angle plug heads. The M21 will work, but IMO it is not the best choice unless you are building a road racer. The M20 or BW Super T10 are much better suited to the 3.54 gear set. The Lakewood scattershield with the Camaro slave is a good choice. Another option is the 84-87 Corvette bellhousing with integral slave. It too is written up in the JTR manual. At least in my older ones. I would think a Hurst Competition Plus for a first gen Camaro would work. THe hurst has removeable sticks and you could find one of many that would work from their catalog if the first gen stick didn't. The first gen moves the shift handle towards the center of the trans where the Z hole is while the 2nd gen offsets it to the side. The 68-74 Corvette shifter is well centered also.

MikeS Posted January 13, 2004 Share Posted January 13, 2004 Welcome to the forum. I have the ZZ4 with a 700r4. For headers I used Hooker blockhuggers for D-port angled plugs # 2100 (I think). The steering shaft clears the header by about 3/8 of an inch. Dist. 1/2 inch from firewall and I did not use the JTR spacers under the crossmember . Check out the pics in the WWW below. Good luck on your project Mike Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted January 14, 2004 Share Posted January 14, 2004 There are other options as well if you want a manual overdrive tranny. There are kits that increase the capacity of the T5 to 600hp or more. And there is always the T56. A great tranny that's hard to bust and it comes with a bonus gear.

DavyZ Posted January 14, 2004 Share Posted January 14, 2004 Mike S, you have a killer car...and about the nicest exhaust system I have ever seen--all stainless, no? From the angle it looks like the sparkplug boot will touch the header...but you have already check that right? What is the clearance with the boot on?

namz7791 Posted January 14, 2004 Author Share Posted January 14, 2004 Thanks to all for your replies! Mike, just curious why you omitted the JTR spacers? Also, are you happy with the performance of the ZZ4? Quote Link to comment Share on other sites More sharing options...
danc Posted January 15, 2004 Share Posted January 15, 2004 I have Heddman Tight Tubes with Fastburn 385 angle plug heads (they are different than a ZZ4) and have not had any problems with the wires or boots getting too hot.. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 15, 2004 Share Posted January 15, 2004 namz, As far as I know, very few of the guys here use those spacers. They are intended to increase hood to air cleaner clearance, but there are enough products out there (air cleaner drop bases etc).
